If you’re talking on the phone every day I don’t really see why you’d have to text as well. It’s a lot to balance work, private life, daily calls, ánd texting on top of that. Personally I don’t think the lack of emojis is anything to be concerned about, I cycle emoji’s over time and definitely started using them less and less over the years.
You could talk to him about how you feel of course, I don’t think there’s anything wrong with doing that.
